Consume Zimbra Get Calendar REST Api in Java

I get this error when I consume the REST Api of Zimbra on Android: must Athenticate java.lang.RuntimeException: Failed : HTTP error code : 401
at ZimbraREST.main(ZimbraREST.java:33). However I am absolutely sure that my login and my password are the good ones and my code was working perfectly fine yesterday, and I did not modify any important stuff linked to this code. This code should get me an xml file that I use to get sync calendar on my app. Thanks for your help. Here is my code:
#Override
protected Void doInBackground(Integer... integers) {
System.out.println("15email_adress=" + email_adress);
System.out.println("15password=" + password);
String dayStart = String.valueOf(integers[0]);
String monthStart = String.valueOf(integers[1]);
String yearStart = String.valueOf(integers[2]);
String dayEnd = String.valueOf(integers[3]);
String monthEnd = String.valueOf(integers[4]);
String yearEnd = String.valueOf(integers[5]);
String[] strings = {dayStart, monthStart, yearStart, dayEnd, monthEnd, yearEnd};
int k = 0;
for(String s: strings){
if(s.length() < 2){
strings[k] = "0" + s;
}
k++;
}
dayStart = strings[0];
monthStart = strings[1];
yearStart = strings[2];
dayEnd = strings[3];
monthEnd = strings[4];
yearEnd = strings[5];
try {
URL url = new URL("https://zmail.insa-lyon.fr/home/" + email_adress + "/Calendrier%20Cocktail?fmt=xml&start=" +
monthStart +
"/" +
dayStart +
"/" +
yearStart +
"&end=" +
monthEnd +
"/" +
dayEnd +
"/" +
yearEnd);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(email_adress, password.toCharArray());
}
});
conn.setRequestMethod("GET");
conn.setRequestProperty("--user", email_adress + ":" + password);
if (conn.getResponseCode() != 200) {
System.out.println("15erreur=" + url.toString());
System.out.println("15erreur=" + conn.getResponseMessage());
System.out.println("15erreur=" + conn.getRequestMethod());
return null;
}
System.out.println(conn.getResponseMessage());
InputStreamReader inputStreamReader = new InputStreamReader((conn.getInputStream()));
BufferedReader br = new BufferedReader(inputStreamReader);
String output;
StringBuilder xml = new StringBuilder();
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
xml.append(output);
}
inputStreamReader.close();
br.close();
conn.disconnect();
System.out.println(xml);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(xml.toString())));
rootElement = document.getDocumentElement();
} catch (IOException | ParserConfigurationException | SAXException e) {
e.printStackTrace();
}
return null;
}

Ok so I had to authenticate the user with the code below:
// Authentication part -------------------
String userpass = email_adress + ":" + password;
conn.setRequestProperty("X-Requested-With", "Curl");
String basicAuth = "Basic " + new String(android.util.Base64.encode(userpass.getBytes(), android.util.Base64.DEFAULT));
conn.setRequestProperty("Authorization", basicAuth);
// ----------------------------------------

Get Authentication error when put object to Azure storage

I am using java to make a REST Api call to Azure, put an object to its storage.
I did this successfully last week but now its now working for some reasons.
The error message is as below:
<?xml version="1.0" encoding="utf-8" ?>
<Error>
<Code>AuthenticationFailed</Code>
<Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:a15f2626-0001-004f-778c-f34383000000 Time:2017-07-02T23:43:20.2826278Z</Message>
<AuthenticationErrorDetail>The Date header in the request is incorrect.</AuthenticationErrorDetail>
</Error>
I don't think this is caused by the incorrect time stamp because the "Date" field and the response time are within 15 minutes. The "Date" field in the header is Sun, 2 Jul 2017 23:38:04 GMT
Here are my java code to generate the token and send the request.
public void putObject(String blobName) {

You could refer to the code below if you haven't solved this Authentication error:

inputStream.read(buffer);
OutputStream out = connection.getOutputStream();

System.out.println("Response message : " + connection.getResponseMessage());

Can't POST data to site using HttpURLConnection on Android

I'm essentially trying to mimic what's been done here through the Android app but for some reason data doesn't get returned as soon as it attempts to post data (it returns fine when I delete the writer.write(finalResult) line).
All I want right now is to be able to search for a user's data once I've sent the username.
Here's my code below:
try {
URL u = new URL(url);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("POST");
c.setRequestProperty("Content-length", "0");
c.setConnectTimeout(timeout);
c.setReadTimeout(timeout);
c.setDoInput(true);
c.setDoOutput(true);
//Attempting to send data!
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", paramValue));
OutputStream os = c.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
String finalResult = getQuery(params);
Log.d("params", finalResult);
writer.write(finalResult);
writer.close();
os.close();
c.connect();
int status = c.getResponseCode();
switch (status) {
case 200:
case 201:
BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line+"\n");
}
br.close();
result = sb.toString();
}
} catch (MalformedURLException ex) {
Log.e("log_tag", "Error converting result ");
} catch (IOException ex) {
Log.e("log_tag", "Error in http connection ");
}
//json code!
//parse json data
try{
JSONArray jArray = new JSONArray(result);
//for each object in our json array
for(int i =0; i < jArray.length(); i++){
JSONObject json_data =jArray.getJSONObject(i);
String address = "";
//Checks for missing data in address - Need a class for all fields
if (json_data.isNull("address")){
address = "N/A";
}
else
{
address = json_data.getString("address");;
}
//read one line of the response
myListView.setText("Username: "+json_data.getString("username")
+" / " + "Name: " + json_data.getString("name")
+" / " + "E-mail: " + json_data.getString("email")
+" / " + "Address: " + address);
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data"+e.toString());
}
}
private String getQuery(List<NameValuePair> params) throws UnsupportedEncodingException
{
StringBuilder result = new StringBuilder();
boolean first = true;
for (NameValuePair pair : params)
{
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
}
return result.toString();
}
And here is my php script:
<?php
$searchuser = $_GET["username"];
$databasehost = databasehost;
$databasename = database;
$databaseusername = username;
$databasepassword = password;
$con = mysql_connect($databasehost, $databaseusername, $databasepassword) or die(mysql_error());
mysql_select_db($databasename) or die(mysql_error());
$query = "SELECT * FROM testusers";
$sth = mysql_query($query);
if (mysql_errno()) {
header("HTTP/1.1 500 Internal Server Error");
echo $query."\n";
echo mysql_error();
}
else
{
$rows = array();
while ($r = mysql_fetch_assoc($sth)){
$rows[] = $r;
}
print json_encode($rows);
}
?>

Since you set the header Content-Length to be 0, the server doesn't even read your content... So anything you send isn't received. You should set Content-Length to finalResult.length().

remove this,
c.setRequestProperty("Content-length", "0");

I want to upload an audio file into server.
I am able upload audio file to server through above code but the file is not working(not playing in system). If u have any idea please help me.

You should be using neither FileReader nor StringBuilder here as it treats the data as characters (encoded according to the default system character set). Really, you should not be using a Reader at all. Binary data should be handled via InputStream, e.g.
final ByteArrayOutputStream out = new ByteArrayOutputStream();
try (final InputStream in = new FileInputStream(file)) {
final byte[] buf = new byte[2048];
int n;
while ((n = in.read(buf)) >= 0) {
out.write(buf, 0, n);
}
}
final byte[] data = out.toByteArray();

Did you check checksum on server? Is it arriving unmodified?
If not, try other method to post files. This one helped me a lot:
/**

* #param params Form data
* #param files
